IPC: G01S15/89
Filed: 1996-01-04
Abstract: A plurality of groups of delay time data corresponding to a plurality of focal distances Fn satisfying a condition that a ratio (Fi - Fi-1)/(Fi-1 - Fi-2) is equal to a constant value higher than one are stored in a focus memory. Therefore, the groups of delay time data corresponding to short focal distances are densely stored.          When a particular focal distance is specified, a plurality of ultrasonic pulses delayed according to a particular group of delay time data corresponding to the particular focal distance are transmitted from a plurality of micro-piezoelectric transducers to a focal point of an organism at the particular focal distance. Thereafter, a plurality of echo signals reflected at the focal point of the organism are received by the micro-piezoelectric transducers, and a piece of tomographic image data indicating a portion of a tomographic image is produced in a signal processing unit. Therefore, in cases where one or more particular focal distances are specified, pieces of tomographic image data indicating a tomographic image are produced according to one or more particular group of delay time data, and the tomographic image is displayed according to the tomographic image data.

Patent CA-2171806-A1 (CA)
Title: Method of testing pipes for leakage
Inventor: ASHWORTH ROGER PHILIP
IPC: G01M3/00
Filed: 1996-03-14
Abstract: Air is passed under pressure into a pipe under test and into a reference chamber connected to the pipe by a valve while recording at intervals of every few seconds the temperature in the reference chamber the temperature in the pipe and the absolute pressure in the reference chamber When the test pressure has been reached the valve is closed and the differential pressure between the pipe and the reference chamber is measured.  The valve is opened to equalise the pressure and then closed again and the differential pressure drift rate is measured.  This is repeated several times.  A computer is used to calculate a creep prediction curve.  A comparison is made to see whether the pressure drift rate due to creep and leak only in the pipe independent of any temperature change in the pipe is trending towards crossing the curve or not.

Patent CA-2180870-A1 (CA)
Title: Helicopter autopilot providing airspeed control
Inventor: DURAND BERNARD
IPC: G05D1/08
Filed: 1995-01-11
Abstract: A novel basic architecture for helicopter autopilots where the conventional fuselage attitude control function is turned into an airspeed control function without resorting to coupler technology. A known fraction of the flight control output signal (24S) is added to a standard fuselage attitude input (1S) and fed to each of the two pitch and roll channels, and the resulting signal (4S) has the new static and dynamic properties needed for the control loop to impart static speed stability to the helicopter throughout the flight envelope. Said novel architecture enables the conventional fuselage attitude signal (1S) to be replaced with an accelerometer signal. By displaying the signal (4S), in particular on a standard attitude indicator instrument (33), rapid changes in fuselage attitudes may be monitored and airspeeds may at the same time be controlled.

Title: Immersion freezer with bottom chamber series of cascading conveyor belts
Inventor: EHNOT DONALD JAMES
IPC: F25D3/11
Filed: 1997-02-26
Abstract: The present invention is an immersion freezer which employs a postcooling chamber. The immersion section of the freezer initially immerses all or part of the items to be frozen (typically food items) in a bath of a liquid refrigerant to impart a crust freeze on the items, which locks in moisture and prevents clumping. The postcooling chamber, located underneath the immersion section, then uses the vaporized refrigerant from the immersion section to complete the freezing process while also maximizing efficiency. The postcooling chamber also imparts agitation to the items (which further prevents clumping) through the use of a series of cascading conveyor belts.
